Hosta plant named ‘Magic Fire’

ABSTRACT

A new and distinct cultivar of  Hosta  plant named ‘Magic Fire’, characterized by its relatively compact plant habit; green and pale yellow variegated leaf color; and light lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

Botanical designation: Hosta fluctuans.

Cultivar denomination: ‘Magic Fire’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta fluctuans, and hereinafter referred to by the cultivar name Magic Fire.

The new Hosta was discovered by the Inventor in a controlled environment in Barneveld, The Netherlands, as a whole plant mutation of the Hosta fluctuans cultivar Sagae, not patented, in June, 1998.

Asexual reproduction of the new cultivar by divisions and by tissue-cultured microplants in a controlled environment in Barneveld, The Netherlands since January, 2004, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Magic Fire have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Magic Fire’. These characteristics in combination distinguish ‘Magic Fire’ as a new and distinct Hosta cultivar:

-   -   1. Relatively compact plant habit.     -   2. Green and pale yellow variegated leaf color.     -   3. Light lavender-colored flowers that are positioned above the         foliage on strong scapes.

Plants of the new Hosta can be compared to plants of the parent, the cultivar Sagae. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar Sagae in the following characteristics:

-   -   1. Leaves of plants of the new Hosta were more cordate than         leaves of plants of the cultivar Sagae.     -   2. Leaves of plants of the new Hosta had broad pale         yellow-colored margins whereas leaves of plants of the cultivar         Sagae had very narrow pale yellow-colored margins.     -   3. Leaves of plants of the new Hosta had eight vein pairs         whereas leaves of plants of the cultivar Sagae had seven vein         pairs.

Plants of the new Hosta can also be compared to plants of the cultivar Liberty, disclosed in U.S. Plant Pat. No. 12,531. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar Liberty in the following characteristics:

-   -   1. Leaves of plants of the new Hosta were much smaller than         leaves of plants of the cultivar Liberty.     -   2. Leaves of plants of the new Hosta had eight vein pairs         whereas leaves of plants of the cultivar Liberty had twelve vein         pairs.

The photograph at the bottom of the sheet is a close-up view of typical flowers and a typical leaf of ‘Magic Fire’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and the following description were about two years old and grown in 17-cm containers in a glass-covered greenhouse and under conditions which closely approximate commercial production conditions during the spring in Barneveld, The Netherlands. During the production of the plants, day temperatures were about 20° C. and night temperatures were about 16° C.
